SPECIFICATION forming part of Letters Patent"No. 274,878, dated March27, 1883.

- Application filed January 31, 1883. (No model.)

To all whom it may concern:

Be it known that I, HEMAN A. BABNARI),Of Moline, in the conntyof RockIsland and State of Illinois, have invented certain new and usefulImprovements in'Flour-Packers; and I do hereby declare that thefollowing is a full,

clear, and exact description thereof, reference being had to theaccompanying drawings, and totheletters of reference markedthereon,which form part of this specification,in which- Figure 1 is aside elevationof one side of my improved packer. Fig. 2 is a sideelevation of the opposite side of the machine. Fig. 3is an elevation ofthe rear of the machine. Fig. 4 is a detail sectional view.

My invention relates to improvements on machinery which is designed forpacking flour, bran, cornmeal, dry paints, and other pulvernlentsubstances, audit has especial relation to thatclass ofpackers havingmovable platforms, on which rests the package to be filled.

The nature of my invention consists,mainly, in providing means forraising the platform, with the package to be filled thereon, by thepower used to operate the paeker,thereby dispensing with weights andsprings for this purpose, as heretofore used, and will be fully understood from the following description, when taken in connection withthe annexed drawings.

In the process of packing flour and other material the motion of theangers on the augershaft forces the material through the packingtubeintothe envelope or package, which rests on a platform, and forces them intogether, the amount of power required being governed by the resistanceof the platform in its descent, which is regulated by a brake-lever anda weight at pleasure to pack the desired amount 7 in each package, noextra pressure being required to force down the platform and package, asthey will descend by their own gravity if not prevented by the brake.When a weight or spring is used, as heretofore, to raise the platformand package, the power of the said weight and spring is constantlyexerted to prevent their descent, and is often of itself more thansufficient to pack the material, especially when flour is being packedin paper or cotton sacks, and hence the material ispacked so tight as tofrequently burst the sacks.

A designates the main frame of the packer;

B, the vertically-movable platform, which is allowed to rise and descendbetween the uprights of the main frame, and on which the sack to befilled is supported.

0 is a horizontal shaft, to which rotary motion is applied by means of abelt or by gearing, which shaft transmits rotary motion to the packingaugers that forces the material into the sacks.

D is a brake-shaft, which extends horizontally across the frame A andprotrudes from each side sufficiently to receive pulleys L M. This shaftD has cone-pulleys cl (1 keyed on it between the uprights of the frameA, and

located in close relation to these uprights, to

serve'as abfutments and prevent end-play of the shaft D.

To the cone-pulleys d d is attached a chain, E, which connects thisshaft D to the Platform B and passes under pulleys applied thereto, asshown in Fig. 3. When shaft D is rotated in one direction, the cuties 61(1 wind up the chain E and raise the platform, and when the motion ofsaid shaft is reversed the platform will be lowered. I

On one end of the shaft 1), outside of one of the uprights of frameA, iskeyed the pulley M, which is a brake-pulley, and to this pulley pressureis applied by means of a lever, a, weight b, and a strap, 0, by means ofwhich the descent of the platform B can be controlled and the pressureused in packing the material is regulated. Onthe opposite end of theshaft D is keyed the pulley L.

F is a short shaft extending across and having its bearings in the rearside of the IOU frame A. On the projecting ends of this shaft Fare keyedpulleys J K. One end of this treadle is pivotedto the lower end of thecompound lever N, the upper section of which is fulcrumed on thebrake-shaft D, at which 'fulcrum the said section is held in place bycollars shown in Fig. 3.

A flanged pulley, H,'is applied on the shaft 0, and connected by a belt,P, to the flanged pulley J on the shaft F, near the'end that has itsbearing attached to the compound lever N. A belt, R, connects the pulleyK to the other end of the shaft F with the pulley L on the brake-shaftD.

The operation is as follows: -When it is desired toraisethe platform B,the attendantraises the brake-lever a by one hand, and with his footapplies pressure to the foot-lever O, which, by means of the compoundlever N, forces the end of the shaft F, to which it is attached, awayfrom the shaft 0, and thus tightens the belt P, which communicatesmotion to this shaft F from the shaft O, which latter is always inmotion when the packer is being operated. The shaft F communicatesmotion to the shaft D by means of the belt R and the pulleys K and L,and as the shaft D revolves it windsthe chain E on cone-pulleys d d andraises the platform B. The moment platform B israised to position thepressure on the foot-lever O is removed and the motion is stopped by theslacking of the belt P. The attendant then removes his hand from theloaded brake-lever a, which will then hold the platform 13 fromdescending by reason of the weight b being brought into play. The belt Pis sufficiently slackened to slip on the pulleyH and not impart anymotion to the shaft F unless said belt is tightened by pressare from thefoot-lever O. The shaft D is arranged to move in one direction only towind up the chain and raise the platform B, and it moves in the oppositedirection to lower this platform. Should the motion of shaft 0 not be inthe right direction to turn the shaft D, required to wind up theplatform with an open belt, then the belt R can be crossed, as indicatedin dotted lines, Fig; 2, which will give the direction of motiondesired. The packingcylinder Sis removably secured to the hopper T,

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination, in a machine for packing flour and other materials,of a verticallymovable platform arranged to be raised by the power whichdrives the machine, all constructed and adapted to operate substantiallyinthe manner and for the purposes described.

2. The combination, in a machine for packing'flour and other materials,of a stationary packing cylinder and a movable platform adapted to beraised by the power employed to drive the packer, all constructed andadapted to .operatesubst'antiallyin the manner and for the purposesdescribed.

3. The combination, in a machine for packing flour and other material,of a verticallymovable platform and devices connected therewith whichwill allow the movements of this platform to be controlled at the willof the attendant bythe same power which operates the packer,allconstructed and adapted to operate substantially as described.

4. The combination, in aflour-packer, of the vertically-movable platformB,fillin g and packing device, the braking device, the toggle orcompound lever N, pulley J, and its belt and pulley connections with theshaft D, bearing cones d d, all constructed and adapted to operatesubstantially in the manner and for the purposes described.

5. The combination of the vertically-movable platform B, thesuspension-chain E, cone-pulleys on shaft D, pulleys L M, thebrake-strap and loaded lever applied to pulley M, the compound leverbearing one end of the shaft D, and the treadle 0, all constructed andadapted to allow the platform B to descend from the packing devices byits own gravity afterasack is filled, substantially as described.

6. In a machine for packing flour and other substances, the combination,with the main frame,of a vertically-movable platform, B, the suspensionelevating-chain E, cone-pulleys on shaft D for this chain, pulleys L M,the compound lever and its treadle, the shaft F, hearing pulleys KJ, thebearings eg for this shaft, and pulley H on shaft 0, all constructed andadapted to operate substantially in the manner and for the purposesdescribed.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
